To all whom t may concern:

Be it known that l, MANUEL HUMBERTO PREZ, a citizen of the Republic of Honduras, residing at `San Fedro Sula,in the Department of Cortez and Republic of Hondu ras, have invented new and useful Improvements in Hand Embroidery Machines, of which the following is a specification.

This invention relatesv to a hand embroidery machine for use in embroidering fabrics, and the primary object of the invention is to provide af device of this character which is readily movable dirigibly over the fabric while the needle is being manipulated, allowing embroidery work of any kind to be easily and expeditiously performed.

A. further object of the invention is to provide an embroidery machine which can be manufactured and sold at a comparatively low cost and which isstrong and durable in construction and rapid and efiicient in action.

A still further object of the'invention is to provide an embroidery machine designed to carry a number ofspools of thread, so that selected threads of different sizes or colors may be used as desired. Y

A still further object of the invention is t provide novel means for guiding the needle and supporting-and guiding the machine on the fabric, whereby the thread loops will be held smoothly pressed down against the fab ric and their withdrawal or breakage or tearing of the fabric prevented.

The invention consists of the features of construction, `combination and arrangement of parts, hereinafter fully described and claimed, reference being had lto the accompanyi-ng drawing, in which Figure 1 is aside elevation of a hand embroidery machine constructed in accordance with my invention. Y

rlhe machine comprising my invention consists of a supporting rod or standard 1 having a reduced threaded upper `end or stein -2 and formed in its lower end with a bore or recess 3, the stem 2 receiving an intern-ally threaded upper head or cap nut 4f, while the recessV 3 receives a tang or stem 5 extending upwardly from a lower head 6 and detachably fastened therein by a set screw or nother suitable fastening device 7. A sleeve 8 surrounds the rod or standard 1 and is provided with a bore 9 contracted at its upper end, as shown at 10, to slidably engage the rod, the main body of ysaid borel being of larger diameter than the rod, and a shoulder 11 being thereby provided at the juncture of the upper end of the bore 9 vwith its contracted portion 10. rlhe bore 9 receives at its lower end bushing 12, suitably iixed therein, and which carries'a needle supporting head 13 having an opening vfor the reception of the upper end or shank portion of the needle 111 and provided with a set screw 15 for detachably fastening the needle in position. rlhe sleeve 8 provides a handle, adapted to be reciprocated upwardly and downwardly on the rod or standard 1, for the purpose of transmitting reciprocating movements to the needle 14. A coiled spring 16 is enclosed in the bore 9 zand surrounds the standard 1 between the shoulder 11 and the bushing 12, said spring being secured at its lower end tothe standard land at its upper end to the sleeve .8 and adapted to be compressed on the downward movement of the sleeve 8 to automatically return said sleeve to its elevated or starting position. The spring thus assists in the loperation of the needle actuating device, and when the device is not in active service holds the handle or sleeve 8 and the needle '14 in a normally elevated position.

' The head 6 has extending outwardly therefrom an arm 17, and said arm 17 is provided with a guide passage 18 through which the needle reciprocates and by which it is positively guided. Pivoted, as at 19, to the base of the head 6 is a presser-foot 2O comprising a plate adapted to ride in contact with the surface of the fabric 21 which is'to be embroidered. This presser-foot is provided at its forward end with yoke arms 22 to receive a roller 23, is provided at its rear end with upturned guard lugs 24, and in advance of its pivot is coupled to the bar the fabric firmly in position while the 17 by a coiled spring 25. Between the spring 25 and the roller 23, the presser-foot is provided with an opening 26 for the passage of the end of the needle carrying the" thread which is to be worked into the fabric. The rollerV 23 operates in conjunction with the presser-foot to adapt the machine to be moved easily over the fabric backwardly Vor forwardly or sidewise or in any direction, and in conjunction therewith serves to press and hold the work threads smoothly Vdown againsttheV fabric and prevent the same from becoming loose, pulled out or broken or. the fabric being torn, the presser-foot and roller also serving tohold the engaged portion of stitches are being made, so that embroidery work of firm and secure character and .of first Vquality can be .quickly performed. Thespring 25 serves by its expansive energy to hold the'presser-foot and roller down to theirl work, and guard lugs operate to prevent the heel of the presser-foot from cutting or tearing the fabric, in the event of the backwardv tilting of the device,and also serve to prevent objectionable downward tilting of the presser-foot and strain on the spring 25v when the machine is elevated from awork surface and not in use, as will be readily understood. v

A collar 27 surrounds the cap nut t and isq ed upon the machine in properworking relation to the embroidering mechanism. This spool carrying frame comprises a pair` of spaced parallel vertically disposed bars 29 and 30, the bar 29 being suitablyV secured at its upper and lower ends, in any durable and rigid manner, to the arms 17 and 28. Alined pairs of eyes or openings 3l are provided at intervals in the length of the bars.29 and 30 and the upper and lower pairs of openings lthereof receive the reduced ends of cross-bars 32 whereby saidV bars 29 and 30 Vare coupled and the bar 30 supported-from the bar 29. The reduced ends of the bars 30 are threaded for the reception `of nuts 33, whereby the bars described may befreadily and conveniently assembled and disassembled, and whereby the bar maybe removed without disturbing the bar 29 or cross bars 32,`for the purpose .of applying or removing the thread spools. The Vother openings 3l in the bars 29 and 8O are adapted to receive the end spindles 34 of spools 35, which are ldifferent species or different colors may be heldin position for ready and convenient use, and so that the thread from any desired spool may be threaded through the needle for use. The construction described provides kusing different kinds -of threads or threads of diiferenti'colors may be employed in a quick andA .convenient manner Y' for `use on the same or different pieces l'of fabric which are to be embroidered atany time.V4 Springs SGsuitably fastened on the spool carrier frame bars29 and 30 are arrangedto bear against the fian'ges of the spools and to exert suiiicient spring frictional `pressurethereon to prevent the'spools VfromV casinilturningA and allowing the thread tounwind, while at the same time permitting the thread t0 wind with suiiicient freedom to feed the'needle in its operations.l 1n the use of the device, thethread is led from any desired spool down through theV eye of the needle, and after the needlehas been thus threaded the device is placed upon Y the fabricV to be worked with the presserfoot 2O arranged thereon, fand then, as the device1is moved as required over the fabric,

the handle 8 is reciprocated Vup ,and-down, resulting in the formation bythe'needle of thread loops in thefabricalong the lines of the intended design, the thread loops lying close to one. side of the fabric and the pros jecting portions at the opposite side ofthe fabric being trimmed'ofl in V.the usual way. The handle is so formed thatthe toolj may be operated and guided simultaneouslyby the one hand of the Voperator engaging said handle, and manipulated back and: forth over the fabric while the needle is being operated to produce the embroidery work. VThis allows any design to beV quickly, accurately'V and convenientlyv followed and, as la' .result of the construction of the presser-foot and its cooperating parts set forth, worlr of theV highest quality'may be produced. Y

Y It will be seen from the foregoing description that the tool is composed of acomparatively small number of working parts, the

`vital portions of whichareflargely concealed and protected from injury, VandV that their construction and mode of assemblage allows the parts to beV easily and conveniently assembled forthe production of the machine and disassembled for cleaning, repairs, replacements or other purposes. Y,These and otheradvantages will be apparent, in addition to those stated, to those versed inthe art without a further and extended description.

Having thus fully described my invention, Y.
